    SmartSolar MPPT Charge Controller - 100V - 50AMPFeatures: Bluetooth Smart built-in The wireless solution to set-up, monitor, update and synchronise SmartSolar Charge Controllers.  VE.Direct For a wired data connection to a Color Control GX, other GX products, PC or other devices  Ultra-fast Maximum Power Point Tracking (MPPT) Especially in case of a clouded sky, when light intensity is changing continuously, an ultra-fast MPPT controller will improve energy harvest by up to 30% compared to PWM charge controllers and by up to 10% compared to slower MPPT controllers.  Load output Over-discharge of the battery can be prevented by connecting all loads to the load output. The load output will disconnect the load when the battery has been discharged to a pre-set voltage (48V model: interface with a relay). Alternatively, an intelligent battery management algorithm can be chosen: see Battery Life. The load output is short circuit proof.  Battery Life: intelligent battery management When a solar charge controller is not able to recharge the battery to its full capacity within one day, the result is often that the battery will continually be cycled between a ‘partially charged’ state and the ‘end of discharge’ state. This mode of operation (no regular full recharge) will destroy a lead-acid battery within weeks or months. The Battery Life algorithm will monitor the state of charge of the battery and, if needed, day by day slightly increase the load disconnect level (i.e. disconnect the load earlier) until the harvested solar energy is sufficient to recharge the battery to nearly the full 100%. From that point onwards, the load disconnect level will be modulated so that a nearly 100% recharge is achieved about once every week.  Programmable battery charge algorithm See the software section on our website for details  Day/night timing and light dimming option See the software section on our website for details  Internal temperature sensor Compensates absorption and float charge voltage for temperature.  Optional external battery voltage and temperature sensing via Bluetooth A Smart Battery Sense or a BMV-712 Smart Battery Monitor can be used to communicate battery voltage and temperature to one or more SmartSolar Charge Controllers Warranty InfoWARNING: This product can expose you to chemicals which are known to the State of California to cause cancer, birth defects or other reproductive harm.

    CYRIX-CT 12/24V-120A Intelligent Battery CombinerThe Cyrix Battery Combiner is a microprocessor controlled heavy duty relay that automatically connects batteries in parallel when one of them has reached a pre-set voltage (indicating that the battery is being charged) and disconnects when the voltage decreases below float level (indicating that one or more batteries are being discharged). Cyrix Battery Combiners are an excellent replacement for diode isolators. The main feature is that there is virtually no voltage loss so the output voltage of alternators or battery chargers does not need to be increased.Please contact your dealer for any returns, repairs or support issues related to this product.

    Orion-TR Smart 12/12-18A (220W) Isolated DC-DC Charger or Power SupplyThe Orion-Tr Smart isolated DC-DC charger serves as a DC-DC battery charger or a power supply (also designed for use as a constant voltage source), offering a wide input and output voltage range. This is especially significant in the case of vehicles with a Euro 5 or Euro 6 smart alternator, which often supplies too low charging voltage even when the engine is running or when extended cable lengths, as is often the case in boats and RVs, lead to voltage drops. In such scenarios, precise and controlled charging is imperative to fully charge the service battery while protecting the starter/input battery from discharge.Bluetooth Smart Enabled Any Bluetooth-enabled smartphone, tablet, or other device can be used to monitor, change settings, and update the charger when new software features become available Instant Readout: The VictronConnect App can display key data, including warnings and alarms, on the device list page without the need to connect to the product Fully programmable Battery charge algorithm (configurable) or fixed output.  Smart Alternator Compatibility: engine running detection mechanism Adaptive 3-Stage Charge Algorithm: Bulk – Absorption – Float For lead-acid batteries, it is important that during shallow discharges the absorption time is kept short to prevent overcharging of the battery. After a deep discharge, the absorption time is automatically increased to make sure that the battery is completely recharged For lithium batteries, the absorption time is fixed; the default is 2 hours Alternatively, a fixed output voltage can be chosen Suitable for Use in Vehicles with a Smart Alternator (Euro 5 and Euro 6 Engines)The built-in engine shutdown detection will stop the converter when the engine is not running. This prevents unwanted discharge of the starter battery (see manual for details).Remote On/OffA remote on/off switch or relay contact can be connected to a two-pole connector. Alternatively, the H terminal (right) of the two-pole connector can be switched to battery plus, or the L terminal (left) of the two-pole connector can be switched to battery minus (or the chassis of a vehicle, for example).All Models Are Short Circuit Proof and Can Be Paralleled to Increase Output CurrentAn unlimited number of units can be connected in parallel.High Temperature ProtectedThe output current will reduce at high ambient temperatures.IP43 ProtectionWhen installed with the screw terminals oriented downward.Screw TerminalsNo special tools are needed for installation.
